viridi-bi'unnea subtus pallidiora; petioli circa 1'5 cm. long., supra 

 canaliculati ; folia juniora gradatim diminuta. Corymbus circiter 

 12 X 8 cm. Pedunculi 3-5-12 cm. long. Bracteae paucae, lanceo- 

 lataB, + 2 cm. long., ultimas capitula appropinquantes filiformes, 

 4 mm. long. Involucri phylla extima 5 mm. long., intermedia 

 10--14 mm., intima 18 mm., omnia dilute viridi-grisea. Corollas 

 maturae baud suppetunt. Achaenia basi callosa, brunnea, 6 mm. 

 long. Pappi squamas 2 mm. long., setas 9 mm. 



The affinity of this is with V. Melleri Oliver & Hiern, from 

 which it differs in foliage and capitula. V. Melleri was redescribed 

 by 0. Hoffmann under the name of V. scabrifolia, and referred to 

 his § Laclmorhiza. To me this section seems unnecessar5^ for 

 since the involucres and pappus yield such excellent sectional 

 characters in this genus, I think it a pity to isolate a few species 

 upon the fact of their having some woolly hairs upon their root- 

 stocks: I agree, however, that if such a character is helpful in 

 the grouping of the species of a large homogeneous genus, like 

 Senecio, for instance, it may well be brought into use.

V. carnea Hiern, to which this is allied, has somewhat different 

 toothed leaves, much smaller heads and involucral leaves, although 

 similar in shape, consistence, and colour, very much smaller. 



No. 2331 cited above has smaller heads (2x4 cm.) than the 

 other, and its involucral leaves a little narrower.
